Consider the topological space $(\mathbb{R}, \tau)$ where $\tau$ is the usual topology on $\mathbb{R}$ of open intervals and consider the set $A = [0, 1) \subset \mathbb{R}$. The closure of $A$ is: Hence we see that the boundary of $A$ is as expected: For another example, consider the set $B = [0, 1) \cup (2, 3) \subset \mathbb{R}$. An alternative to this approach is to take closed sets as complements of open sets.
